Reverse part of commit 8b5e9eadb1.
Shouldn't use get_obj_location(obj,...) to try to figure out if obj
has been deleted. That routine uses obj->where rather than scanning
the various object lists and doing that when obj has been deleted
would access stale memory.
A zap from a wand of striking shouldn't hit a drawbridge if it is
just passing over the span's spot when the bridge is closed. This
change matches the 3.7 behavior when the zap is performed by the hero.
It does hit if passing over that same spot when the bridge is open or
if it hits the portcullis spot whether open or closed.
Also, simplify the handling for the wand's destruction. It still
ends the zap early if that happens even though logically the rest of
the zap range should still be targetted.
Report was for an impossible "What an interesting effect (%d)" which
the fuzzer turned into a panic. Monster on the drawbridge zapped
toward the open portcullis, destroying the bridge and killing itself.
Wand was made of wood and burned up in lava under the fallen span.
Freeing the object zeroed it rather than leaving stale data, and the
zap continued while referencing freed memory that looked like it had
type STRANGE_OBJECT, triggering the impossible.
This will make a monster-induced zap stop early if a drawbridge
incident destroys the wand. That isn't the best possible fix
because the zap should continue despite the wand's destruction, but
at least it will now avoid triggering "intestsing effect".
If a monster fled from the hero by intentionally jumping into a vault
teleporter located in a niche which was still hidden and the hero
saw it happen, the trap would be mapped but the niche would remain as
a secret corridor spot. The hero couldn't move onto the trap until
searching or wall kicking or other map disclosing activity converted
the spot into regular corridor.
Trap doors in hidden niches did already change the secret corridor
into normal corridor to unhide the trap's spot, but only if the hero
saw it happen. Now the terrain change occurs even if hero doesn't
see it; only mapping the trap depends on that.
While testing the fix, I noticed that a monster jumping onto a vault
teleporter was teleporting randomly rather than being sent to the
vault, unlike when triggering such a trap by accident. The code has
changed for 3.7 but this bug was already present in earlier versions.
Issue reported by elunna: hero witnessing a wand of striking being
zapped by a monster didn't have that type of wand become discovered.
Monsters observing hero resisting--or failing to resist--the effect
on hero didn't learn about target's current resistance capability.
Barely tested.

cg.zeroobj was originally added (under its previous unprefixed name)
for providing a one-line way to zero out the fields of a struct obj.
struct obj tempobj;
tempobj = cg.zeroobj;
initfn(struct obj *otmp)
{
if (otmp)
*otmp = cg.zeroobj;
}
More recently, the address of cg.zeroobj began to be used as a return
flag to indicate some things, but the 'const struct obj zeroobj' wasn't
an ideal fit for the purpose and required a number of casts, including
casting away const.
Provide a better fitting variable (gi.invalid_obj) and eliminate a
number of casts.
Issue reported by vultur-cadens: changing helm of brilliance to
crystal made it stop being classified as "hard helmet" so it gave
less protection against things falling onto the hero's head.
Change the is_metallic() tests used on helmets to new hard_helmet().
Unlike when thrown, crystal helmets don't break when objects fall
on them.
Fixes#1060
Redo the check for whether a monster is Vlad when deciding whether to
keep it out of a bones file. Use the new check in find_defensive()
where Vlad won't waste a turn attempting to use a wand of digging when
in his undiggable own tower. (Failing to check for vampshifted Vlad
in the latter case wasn't actually a bug because if/when shifted,
he's unable to use items so couldn't attempt to use wand of digging.
Switch to the new check anyway.)
Reported by copperwater "on behalf of Maud": when hero hears an
unseen monster read a not-yet-discovered scroll of create monster
and doesn't see any new monster appear, the player is given a chance
to call the scroll something. When hearing an unseen monster read
a not-yet-discovered scroll of teleportation, the label is revealed
but no such 'call it' opportunity is offered, so the player could
deduce which of the two scroll types it was for either case.
Provide an opportunity to supply a 'called' name for scrolls of
teleportation when heard being read, same as with create monster.
Surprisingly complicated to achieve.
Eliminated a couple of goto's in the process.
Fixes#1046
I was working on this at the time 3.6.0 was released and set it aside
until later. Later has finally arrived. Redo the Blind, Blinded,
Blindfolded,&c macros to make more complete use of intrinsic property
handling. Blinded was being treated as a number which could be added
to or subtracted from; now that has to be done via TIMEOUT mask
because it has FROMOUTSIDE (OPTIONS:blind) and FROMFORM (poly'd into
!haseyes() form) bits included. Object definitions for blindfold and
towel now specify the BLINDED property; overriding blindness via the
Eyes of the Overworld is accomplished via props[BLINDED].blocked.
Code generated for the scores of Blind and !Blind tests throughout
the program should be smaller.
One bug that has been fixed is that putting on the Eyes of the
Overworld cured permanent blindness (from OPTIONS:blind). The
u.uroleplay.blind flag was cleared and stayed so after taking them
off. Putting the Eyes on still breaks blind-from-birth conduct but
now blindness will resume when they are removed.
This was untested at the time it was set aside and is only lightly
tested now. A large number of the changes here are just to switch
from Blinded to BlindedTimeout for current timed value and to call
set_itimeout() for setting a new value.
Heroes recognized unseen same-race monsters by voice, but it yielded
an unexpected result if the monster was unique. Change it so that
hero will recognize any type of monster by its voice if that monster
has been seen and limit unseen same-race ones to non-unique monsters.
Treats shopkeepers as unique since they have distinct names.
This adds a new flag to struct monst in order to track whether each
specific monster has ever been seen or sensed.
Extend "killed by the touch of death inflicted by <monster>" to buzz().
"Killed by a bolt of cold" becomes "killed by a bolt of cold zapped by
<monster>" or "killed by a blast of cold" becomes "killed by a blast
of cold exhaled by <monster>" and so forth.
More work than expected; the zap code isn't passed enough context.
BZ_M_WAND() was producing the wrong value for wands zapped by monsters.
sound_verbal(char *text, int32_t gender, int32_t tone, int32_t vol,
int32_t moreinfo);
-- NetHack will call this function when it wants to pass text of
spoken language by a character or creature within the game.
-- text is a transcript of what has been spoken.
-- gender indicates MALE or FEMALE sounding voice.
-- tone indicates the tone of the voice.
-- vol is the volume (1% - 100%) for the sound.
-- moreinfo is used to provide additional information to the soundlib.
-- there may be some accessibility uses for this function.
It may be useful for accessibility purposes too.
A preliminary implementation has been attempted for macsound to test
the interface on macOS. No tinkering of the voices has been done.
Use of the test implementation requires the following at build time with make.
WANT_SPEECH=1
That needs to be included on the make command line to enable the test code,
otherwise just the interface update is compiled in.
I don't know for certain when AVSpeechSynthesizer went into macOS, but older versions
likely don't support it, and would just leave off the WANT_SPEECH=1.
If built with WANT_SPEECH=1, the 'voices' NetHack option needs to be enabled.
It was a bit strange, when I first started up the test, to hear Asidonhopo,
the shopkeeper, talking to me as I entered his shop and interacted with him.
Reported by elunna: a monster trapped in a pit or web that was
adjacent to a polymorph trap could enter that trap to change shape.
It would remain flagged as trapped but there's no way to escape
from a polymorph trap so it would be stuck.
Fix supplied by entrez: when a monster is picking MUSE strategy,
don't allow it choose "enter polymorph trap" if it is currently
trapped.
I entered the changes from the diff manually and added a bunch of
minor formatting bits.
Fixes#972
Insert the calls to trigger a number of potential soundeffects
into the core.
If no additional soundlib support is integrated into the
build, then the Soundeffect macro (sndprocs.h) expands to nothing:
[#define Soundeffect(seid, vol)
]
If, however, at least one additional soundlib support is integrated
into the build, then the Soundeffect macro gets defined as this
in sndprocs.h:
[#define Soundeffect(seid, vol) \
do { \
if (!Deaf && soundprocs.sound_soundeffect \
&& ((soundprocs.sndcap & SNDCAP_SOUNDEFFECTS) != 0)) \
(*soundprocs.sound_soundeffect)(emptystr, (seid), (vol)); \
} while(0)
]
That macro definition checks for the hero not being Deaf; it checks
to ensure that the active soundlib interface has a non-null
sound_soundeffect() function pointer; and it checks to ensure
that the active soundlib interface has declared that it supports
soundeffects by setting the SNDCAP_SOUNDEFFECTS bit in its sndcap
entry. That just means that the interface routines are prepared to
accept and deal with the calls from the core, whether or not it
actually produces the desired soundeffect.
The consolidation of global variables from scattered source
files into decl.c and declared in decl.h was begun in 3.7.0.
Their placement in common files was done for centralized
initialization and potential re-initialization during a
"play again" scenario.
It wasn't really necessary for all of them to be housed in a
single huge structure to meet the "play again" requirement,
and the single huge structure has been a little unwieldy when
it comes to maintenance.
Following this commit, instead of one single extremely large structure
named 'g' to house all of the relocated global variables, they
are distributed into several ga through gz.
To make things easy for the developer, each variable is placed
into the struct corresponding to the starting letter of the variable.
That way, no lookup is required in order to know which struct houses
a particular variable, it is a simple match to the starting letter
for all the centralized global variables.
A global variable named 'amulets', would be found in ga.
ga.amulets
^ ^
A global varable named 'move', would be found in gm.
gm.moves
^ ^
A global variable named 'val_for_n_or_more' would be found in gv.
gv.val_for_n_or_more
^ ^
A global variable named 'youmonst' would be found in gy.
gy.youmonst

Issue reported by AndrioCelos: bullwhip using monster was able to
snatch hero's weapon when hero was engulfed.
Fix is trivial: when a monster is choosing an item to use, don't
pick bullwhip if hero is engulfed. Regular attack attempts already
skip engulfed hero.
Fixes#935
Issue reported by Melon2007: when non-deaf hero heard an unseen
monster read a scroll, the monster's type was identified accurately
(unless distorted by hallucination). That was intentional but it
doesn't seem plausible for the hero's hearing to be that acute.
Change it to report the monster type accurately if not hallucinating
and monster is the same species as the hero (as the current form if
hero is poly'd), otherwise report it as "someone" when it's humanoid,
otherwise as "something".
Also, if the monster is heard at a spot that would be visible if
hero could see, draw a "remembered, unseen monster" glyph there.
Fixes#934
Short for distu(mtmp->mx, mtmp->my) (i.e. the distance between the hero
and the specified monster), which is a very common use of distu(). The
idea is that this would be a convenient shorthand for it; I actually
thought it (or something very similar) existed already, but couldn't
find it when I tried to use it earlier. Based on the number of uses of
fully-spelled-out 'distu(mtmp->mx, mtmp->my)' replaced in this commit
I'm guessing I just imagined it.
The pull request included some changes that were neither accidental nor

If a monster cannot move, for example because it's being
blocked off by boulders or walls, it will try to escape by some
method - such as a wand or scroll of teleportation.
Previously monsters used wands of teleportation at hero, if hero was
standing on top of stairs, or on a scary thing (eg. Elbereth or
scroll of scare monster).
Allow monsters to recognize when hero is behind a chokepoint and
monster has friends with them, hopefully teleporting the hero
out of the chokepoint.
... using the same hack when zapping themselves: If the level is
no-teleport, the monster will learn of teleport traps, and if
it knows about them, won't try using teleportation again.
According to comments in the code, this feature was disabled
because it never triggered, making it useless. I enabled the code
again, and monsters demonstrated a willingness to zap the player
with wands of teleportation. I am not sure of what exactly changed,
but I think this feature could trigger some interesting situations,
and absolutely deserves to make a comeback.
When the hero zaps a wand of digging down in an undiggable level, it
creates a pit. When a fleeing monster did the same thing, it had no
effect. Bring this closer to the behavior experienced by the hero: if a
monster tries to use a wand of digging to create a hole in an undiggable
floor, a pit will be made (and the monster will fall into it, if not a
flyer).
Add macros to convert AD_foo, WAN_foo, and SPE_foo to relative values
for passing to BZ_U_foo and BZ_M_foo macros.
Change some return values in monster spellcasting function from
magic numbers to MM_MISS or MM_HIT.
Make buzzmu consider hero resistances - previously the
monster with innate zapping ray (Angels and Asmodeus) would
just keep doing that attack, but they will now just curse if
it saw the hero resist the attack.
Make monsters being created in Sokoban that are given a random
defensive item be less likely to receive a wand of digging. Should
result in fewer extra holes needing to be plugged.
Resurrected from an old stash entry. I have no recollection of why
I didn't consider it to be ready for prime time way back then.
This is a descendent of an earlier patch I wrote. The main idea is still
to clearly communicate to the player *what* something is turning into,
without the need to farlook afterwards, and give them the opportunity to
add MSGTYPE for when something jumps on a polymorph trap and becomes an
arch-lich. If it happens out of sight, the player also might get a whiff
of the monster's smell, giving a bit of advance warning.
There is one new case in here, in normal_shape(), which came about
because I noticed a weird message sequence: "The magic-absorbing blade
cancels the python! You kill the chameleon!" with no intervening
message indicating the python reverted to a chameleon.
trycall() is a short docall() wrapper that is a no-op if the item is
already identified or the player has called the object type already. For
some reason, many calls to docall() did those same exact checks
beforehand.
This commit eliminates that redundancy by converting those calls into
trycall(), which is now made extern rather than local to do.c. No
behavior should be changed by this commit; I've checked that none of the
affected places could take a different code path now that the
oc_name_known and oc_uname checks are removed.
Move some code that was used to decide whether to call distant_name
or doname into distant_name so that the places which were doing that
don't need to anymore and fewer places can care about whether an
artifact is being found. There were two or three instances of
distant_name maybe being called, based on distance from hero, and
yesterday's artifact livelog change added two or three more and made
all of them override the distance limit for artifacts.
After that change to distant_name, make sure that conditional calls
to it become unconditional--just not displayed for the cases where
!flags.verbose had been excluding them. That way distant_name can
decide whether an item is up close and arrange for xname to find it
if it as an artifact.
Also, implement an old TODO. Wearing the Eyes of the Overworld
extends the distance that an item can be from the hero and still be
considered near anough to be seen "up close" when monsters pick it
up or drop it. The explicit cases were using distu(x,y) <= 5, the
distance of a knight's jump. Each quadrant around the hero is a 2x2
square with the diagonal corner chopped off. The replacement code in
distant_name calculates a value of 6, which is functionally equivalent
since the next value of interest beyond 5 is 8. Wearing the Eyes
(deduced by having Xray vision) extends that threshold an extra step
in addition to overriding blindness and seeing through walls: 15,
a 3x3 square in each quadrant, still with the far diagonal corner (16)
treated as out of range.
